I use a Weller dual-heat gun for larger items such as switches, connectors, etc. For circuit boards or things requiring low heat, like semiconductors, I use a cordless (rechargeable) soldering iron. The one I use is the Wahl Isotip (about $60 or so, I think). Radio Shack has had cordless soldering irons off and on. I don't know if they currently do. The cordless iron is an instant-heat, fast cooling tool, and can accomodate several different types of tips, including a tip for clearing bridged connections. Actually, there is a knife tip which I prefer for that job. You can position the tip and the solder on the connection while everything is cool, just as with the gun. The "iron" has a pushbutton to hold down rather than a trigger. By holding the solder vertically on the connection and touching the tip, you can feel the heat traveling up the solder so that you know that heating is occuring and feel the solder descending toward the work as it melts, so you can get an idea of how much solder you are applying. The cordless iron is a compromize; not as efficient as an electric iron. But an iron that stays hot all the time requires really good orientation and lots of practice. I don't do enough soldering any more to stay proficient, but the cordless iron meets my needs, and there is no cord to inadvertently burn and contaminate the tip with. 73. -- Mike, K9AZS
